THE PARTICLES CAN BE ADMINISTERED PARENTERALLY FOR DIAGNOSTIC, PROPHYLACTIC OR THERAPEUTIC PURPOSES. ON ADMINISTRATION IN THIS WAY, THEY ARE BROKEN DOWN OR SOLUBILIZED BY THE BODY FLUIDS OVER A PREDETERMINABLE PERIOD RANGING FROM MINUTES TO SEVERAL DAYS, WHEREUPON THE RADIOISOTOPIC MATERIAL IS EXCRETED FROM THE BODY THUS LIMITING EXPOSURE TO THE RADIATION.
